Dog Has Bloody Poop: Should I Call My Vet? | Dr. Nancy Reese Deep Dive

Bloody poop is scary! Dr. Nancy Reese weighs in on potential causes, when to be concerned, and what you can do to help your pup at home.


The only thing worse than your dog having diarrhea is your dog having bloody diarrhea. Nasty! The good news is, one episode of bloody stool is not usually anything to worry about, and cancer is not a common cause.

If your dog’s stool has blood in it or is black (a sign of bleeding in the stomach or small intestines), let your vet know. If it only happens once your dog may not need treatment, but this way your vet can put a note in your dog’s record about when these things happen.

Bloody stool is a concern if: It happens multiple times; There is a lot of blood; The dog strains to poop; The dog is also vomiting; The dog is acting ill or painful

All of these cases benefit from a veterinary exam and a fecal sample analysis to look for parasites and other abnormalities.

Tune in for more of the causes of bloody stool, plus what you and your vet can do about it.
